To all whom it may concern 4 Be ih known that I, HENDRIK STUKART, a subject of the Ruler of the Netherlands, and resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Slicing- Machines, of whieh the following is a speci-l fication. 0

This invention relates in general to 1mprovements in slicing machines of the type embodying a reciprocating carriage and an .cle support with respecttothe carriage.

To the attainment of these ends and the accomplishment of other new 'and useful objects as will appear, the invention consists in the features of novelty, in substantially the construction, combination and arrangement `of the several parts, hereinafter more fullydescribed and claimed and shown/in the accompanying drawings, exemplifying the invention, and' in Which,-

Figure 1 is a top plane view of a slicing machine, having an attachment applied thereto, constructed in accordance with the principles of this invention, and with parts removed and parts bro-ken away; for the sake of clearance; Fig. 2 is a. longitudinal sectional view as takenjon line 2-2 of Fig. 1; Fig. 3 is a sectional view as taken on line 3 3 of Fi 1; Fig. 4 is a detail view in elevation o a portion of the feeding mechanism. x

Referring more particularly to the drawings, the carriage designated generally by the reference numeral 10 vmoves adjacent the cutter 11, and is reciprocatedupon the guides 12, 13, by means of a crank 14 connected to a shaft 15 supported by the base 16, and which crank is connected by means of a link 17 with vthe carriage, so that when the hand Wheel 18 is operated, the shaft 15 will be rotated, and a reciprocating movement be instar-ted 'to the carriage.

A shaft 19` is Journaled in suitable bearings 20, carried by the carriage 16 and this shaft is located below, and preferably adjacent the center of the meat table to be hereinafter described. 'Arranged adjacent one end of the shaft 19 is a clutch element 21, which is secured to lthe shaft for rotation therewith by means of a suitable fastening device 22. A sleeve 23 is mounted loosely upon the shaft 19 and connected with the sleeve is another clutch element 24 which coperates with the clutch element 21. This sleeve 23 is adapted to be shiftedlcngitudinally on the shaft 19 by means of a crank arm 25, which is connected with a shaft 26 journaled in suitable bearings, and which crank arm is provided with a projection-27 enteringa circumferential groove 28 in an enlarged portion 29 arranged preferably adjacent the other end of the sleeve'23. This enlarged portion. 29 is provided with a clutch face 3 0, which ccperates with another clutch element 31 mounted looselynpon the shaft 19. This clutch element 31 is mounted loosely upon a sleeve 32 having an enlarged portion 33 and the sleeve 32-is in turn connected with a sleeve 34 for rotation therewith, the latter being directly journaled upon the shaft 1'9, and having connected thereto a pinion 35, which pinion `meshes with a rackcarried by the lower face of the guide 13, so that as' the carriage is reciprocated the pinion 35 will ,be rotated first in one direction and then in the other, according to the direction of movement of the carriage.

A ylelding connection is provided between the clutch element 31 and the sleeve 32, preferably in theyform of spring controlled pins 36, which engage in coperating teeth 37 on the adjacentl face of the enlarged portion 33 of the sleeve. This 'yielding connection is provided for the' purpose of preventing movement of'the meat plate upon the inovemeint of the support to the right in Fig. 1, which movement of the support would cause the meat plate to move forward, but to permit movement of the meat plate u pon the completion of the cutting stroke and the beginning of the return stroke to retract the Same until the actuation of the lever 58 by' the pin 60.

icunted upon the sleeve 23 is a worm gear 38 which is connected to the sieeve fory rotation therewith by means of keys or feathers 1 with respect to tue worm gear. In order to hold the gearv against longitudinal movement 'during the shifting of the sleeve, the worm gear is providedl with a ortion having a circumferential groove 40 into which a projection 41 on the carriage 16 extends, there by permitting the worm gear to rotate with the sleeve, and holding it against movement longitudinally when the sleeve is shifted.

Meshing with the worm gear 38 is a worm 42 which latter rotates about an axis 43 ar- -ranged at right angles to the shaft 19, and connected withv this worm 42 foi` rot-ation therewith is a pinion gear 44, which meshes with a. rack 45 carried bythe bottom of the feed table 46, and which latter has a bearing directly upon the ,carriage 1-6, as shown more clearly in Fig. 3.V Thus it will be manifest that when the shaft. 19 is rotated, the sleeve 23 will be rotated. This in turn will impart a rotary movement to the worm 38, which latter rotates the worm 42 and in turn the pinion gear 44, thereby causing the feed table 46 to be advanced or( retracted with respect to the carriage 16 according to the direction of rotation of the worm 38'.

The feed table 46 is held against displacement with respect to the carriage 16 in any suitable manner,a simple and efficient means embodies pins 46 which project through portions of the carriage 16 and into grooves 47 in the adjacent faces of the feed table and which grooves extend longitudi- -nally of the table, so that the reciprocating movement of the feed table with respect to the ,carriage will not bev interferred vvlth. Elastic elements 48 are provided for 'holding the pins in position and screws 49 are also provided lfor vholding the elastic elements against displacement.

A meat plate 50 is arranged above thel feed plate 46 and has a bearing directly upon the carriage16, and this plate 50/ is connected with the feed `table in any suitable manner, such as by means of a separable fastening device 51, although any form of fastening device may be employed.

An intermittent movement is imparted to the shaft 19 preferably by means of a ratchet gear 52, secured to the shaft, and with which gear a dog 53 coperates. This dog is mounted upon an arm 54 pivotally supported preferably bylthe shaft 19, and an extension 55 on the arm carries an antifriction device 56 Whichcoperates with a cam 57 secured to any fixed portion of the machine. so that when the carriage is reciprocated, the anti-'friction device will pass across the `cam 57 and move the dog in a direction such that it will coperate with the teeth of the ratchet 52 and thereby impart a step of rotation to the shaft 19. A crank 58 may also be connected With the shaft 19 for rotating it.y

With the me hanism thus far described,

it will be manifest that as the carriage is reciprocated, the pinion 35, which is in engagement with the rack on the guide 13, will be rotated in first one direction and then the other, and as long as the clutch elements 30 and 31 are.out of engagement witheach other this motion of the pinion 35 will have no effect upon the shaft 19, and during this time the pawl and ratchet elements 53,52, Will intermittently operate the shaft 19 and if the clutch elements 21, 24, are in engagement with each other, the feed plate will be .o

advanced .tb present a' new portion of the uncut material to the cutter. In order, therefore, to utilize this motion of the pinion 35 to return the feed and meat plates, all that is. necessary is to disconnect 'the clutch elements 21, 24 and move the clutch elements 30, 31 into operative relation. In this position, the motion imparted to the pinion by the rack on the guide 13, will rotate the worm 38 and consequently the worm 42 and pinion 44 in the opposite direction, and the pinion44 will, through the medium of the rack 45, automatically return the meat and feed plates.

To automatically render the respective clutch elements active and inactive and to shift the sleeve 23, the crank shaft 26 and crank 25 are provided, and these are automatically rrocked by means of an arm 58, which is connected to the crank shaft 26, and is arranged beneath the feed plate 46.

Spaced projections 59, 60 are arranged on the bottom of the feed plate between which the arm 58 extends, and these projections are so disposed with respect to each other that just as the feed plate is about to reach the limit of its forward movement one of the projections will engage the arm 58 to shift it and rock the shaft 26 to move the-sleeve 23 in one direction, and when the feed plate is about to reach the limit of its movement in the opposite direction, the other projection will engage and shift the arm 58 as well as the sleeve 23. Thus, it will be manifest that the sleeve 23 will be automatically shifted by the movement of the feed plate with respect to the carriage, and this' automatic shifting of the sleeve in one direction will render active the parts which will connect the pinion 35 with the sleeve 23 and thereby allitomatically and positively return the feed p ate. j

In order to insure a positive action of the sleeve 38, a lever 61 is rovided which is connected with themcran shaft 26 and is provided with a projection 62 and a second lever 63 having a tapered or cam-shape portion 64 is arranged at right angles with the lever 61 and an elastic member 65 is con-yv nected with the lever 63 and a xed portion of the carriage and operates to normally hold the tapered portion 64 of the lever in engagement' with the projection 62 on the vanced to a predetermined lever 61. When the extremity of the taperedv portion 64 is in Contact with the projection 62, the sleeve 23 will be held in an intermediate position, that is, so that the clutch elements 21, 24 and 30,31 will be inactive with respect to each other. When, however, the arm 58 is shifted and the shaft 26 rocked, the projection 62 of the 'lever 61 will be shifted and the spring 65 will cause one or the other of the inclined portions or faces 64 to move against the projection- 62 and thereby assist in shifting the sleeve 23.

In order to return the feed plate from any point to which it has been advanced, and at any time, the lever 61 is provided with a handle 66 arranged in a convenient position for the operator, and which may be grasped by the operator and shifted when desired.

In order to prevent overthrow of the shaft 19, under the iniiuence of the p'awl and ratchet mechanism, a friction device 67, controlled by an elastic member 68 may be' provided, and which cooperates with the shaft 19.

With this improved construction it will be manifest that all of the parts are compactly arranged and the feeding mechanism is not only mounted upon Athe carriage, but is concealed and protected thereby, the only portion of the feeding mechanism which projects above the top of the carriage 16 being the pinion 44, and this pinion is itself protected and covered by the feed plate, the latter being of sucha length that the pawl and ratchet mechanism will also be covered and protected-thereby in any position of the feed plate with respect to the carriage.

Whilein the present exemplication of this invention the preferred form or construction and" arrangement of the several parts are herein shown and described, it is to be understood that numerous changes may be made in the details of construction and in the combination and arrangement of the several parts, without departing from the spirit of this'invention.

With this improved arrangement of feed plate and meat plate, it wilt be apparent that one or bo-th may be readily removed or attached without interfering with anyof the remaining portions f the mechanism.
